  7. 5. On Biogenic Halocarbons in Antarctic Waters

    Författare :Erik Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volatile biogenic halocarbons; Antarctica; Southern Ocean; Sea ice; Snow; Air-sea exchange;

    Sammanfattning : Little is known regarding the distribution of naturally produced volatile halogenated organic compounds, halocarbons, in Antarctic waters and the contribution of these waters to the global atmospheric load of halogens. In the atmosphere, halocarbons are degraded by photolysis, and form reactive halogen radicals. LÄS MER
